BudsGunShop.com - Is this 10MM an alloy frame or steel?

Direct from a SIG representative. "The P220 10mm Legion model has a stainless steel slide and frame. Only the .45 ACP models have an alloy frame and stainless slide."

All p220 sigs in 10mm are steel not alloy. Made from steel to handel the higher power 10mm.

the sig P series are alloy frames "The slide of the P220 series is a heavy-gauge sheet metal stamping with a welded-on nose section incorporating an internal barrel bushing. The breech block portion is a machined insert attached to the slide by means of a roll pin visible from either side. The frame is of forged alloy with a hard-anodized coating."

Dustin, this Sig 10mm has an Alloy Frame with Legion Gray Finish & Carbon Steel Slide with Legion Gray Finish. ****Since different vendors list it as either Alloy or Steel**** I'm pretty sure it is Alloy but you can confirm directly with Sig Customer Service at 603.610.3000 option 2 - Monday-Friday: 8:30am – 5pm EST
